As of BV 1.0, only single bean properties can be validated using Validator#validateValue(). It would be useful if also complete property paths could be validated in a similar manner.
If we officially support it we need to:
standardize the String representation of a Path, which is something we shied away from in 1.0
offer an alternative methods accepting Path; we would also need to offer a PathBuilder of sort
